876538 divided by 23 
The aim is to understand the frequency of 23 in 876538.

Going ahead to step 1:
If we divide 8 by 23, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 23

Moving on to step 2:
If we divide 87 by 23, we get 3 and a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 69 from 87, we get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 23

Moving on to step 3:
23 goes into 186 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we take 184 away from 186, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 23

Advancing to step 4:
If we divide 25 by 23, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 381.0
The remainder is 2 after subtracting 23 from 25.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 23

Advancing to step 5:
If we divide 23 by 23, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 3811.0
If we subtract 23 from 23, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 23

Advancing to step 6:
The number 23 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 38110.0
If we subtract 0 from 8, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
23 goes into 80 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 38110.3
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
If we divide 110 by 23, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 38110.34
The remainder is 18 after subtracting 92 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
When dividing 180 by 23, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 38110.347
If we take 161 away from 180, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
23 goes into 190 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 38110.3478
If we subtract 184 from 190, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
The number 23 fits into 60 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 38110.34782
Subtracting 46 from 60 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
When dividing 140 by 23, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 38110.347826
Subtracting 138 from 140 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
23 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 38110.347826
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
23 can be fit into 200 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 38110.34782608
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 38110.34782608 with a remainder of 1.6e-08.
